RULER. Y

SPECIFICATION forming part of Letters Patent No. 637,832, dated November28, 1899.

Application filed February 10, 1899. Serial No. '705;210. (No model.)

T0 a/ZZ whom, it muy concern.'

Be it known that I, MEYER RosENBERc., a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Rulers, of whichthe following is a specification.

This invention relates to that class of rulers which are provided withinked marking- Wheels adapted to print lines on the surfaces over whichthey are caused to roll; and the object of myimprovemeut is to provide adevice of this kind that will be efficient in operation, neat inappearance, and inexpensive in the cost of manufacture.

Referring to the accompanying drawings, Figure l is a sectional frontview of the device. Fig. 2 is a side view of same. Fig. 3 shows amodified form of the invention.

Similar lettersrefer to similar parts throughout the several views.

A represents a stem or handle having a reduced portion A at its lowerend. Permanently secured to this portion is an ink-receptacle consistingof a tube B, having an -o eninfr B', through which the ink is insertedsaid opening extending through the wall of the tube and situated in theupper portion thereof. The lower end portion of this tube has a reducedthreaded or corrugated portion B2, in which is adjustably secured a plugC, made of felt or some other absorbent material, said plug serving asan ink-pad for the marking-wheel hereinafter mentioned.

The purpose of having the reduced portion of the tube provided withthreads is to permit the plug to be adjusted longitudinally by slightlyturning the same and also to prevent the plug from being accidentallypushed back into the tube.

D is an outer tube slidably mounted on the inner tube B above referredto and extending beyond the lower end thereof. The lower end portion ofthe outer tube is split and terminates in two downwardly-directedtongues D'. Revolubly mounted between these tongues is an annularmarking wheel or disk E, said wheel being normally in contact with theabsorbent plug and is adapted to print lines on the surfaces over whichit is rolled.

In order to prevent the outer tube from rotating, the same is providedat its upper portion with a slot F, adapted to engage a stud G, which issecured to the inner tube.

The object of the reduced portion of the inner tube is to expose a largesurface of the plug to the ink, and thus cause the same to be quicklyabsorbed and transmitted to the lower contact-surface of the plug. Inthe modified construction illustrated in Fig. 3 this is accomplished byreducing the upper portion of the plug. In this construction the ink isinserted at the top of the inner tube, the same being for that purposeremovably secured to the handle by having interior screwthreads, whichengage corresponding threads cut on the reduced portion of the handle.

In using the ruler the outer tube is removed, the plug properlyadjusted, and the ink inserted through the exposed opening in the innertube. The outer tube, with the markingwheel secured at its lower end,isthen put back over the inner tube, care being taken that the slot on theupper end portion of the outer tube engages the stud projecting from theinner tube. The ruler is then ready for use. Byrolling the marking-wheelover the surface to be marked the wheel will print a solid sharp line,the periphery of the wheel being continually inked by the plug or pad. Aplurality of lines may be drawn by mounting several wheels side by sidebetween the tongues, these being for that purpose capable ofspreadingapart. By using marking-wheels of different tbicknesses heavy or lightlines may be drawn.

This ruler is designed for drawing marginal lines in blankbooks,billheads,&c. The simplicity of its construction and smallrequirements of care and adjustment render it particularly adapted foruse in commercial offices.

Being aware that changes may be made in the construction herein shownwithout departing from the spirit of my invention, I do not desire tolimit myself to the use of this particular combination of parts.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. In a ruler, the combination with a stem or handle, of anink-receptacle comprising an inner tube secured to said handle, saidtube being provided at its lower end with a reduced threaded portion,and an opening eX- IOO tending through the wall of the said tube in theupper portion thereof, au absorbent plug adj ustably secured in the redueed portion of said tube, an outer tube slidably mounted on the innertube, the lower end portion of said outer tube being split in two andterminating in two downwardly-directed tongues extending beyond thelower end of the inner tube, a marking-wheel revolubly mounted betweenthe said tongues and normallyin Contact with the absorbent plug, andmeans for holding the outer tube against rotation, substantially asdescribed and for the purpose set forth.
